You don’t have to parler français to recreate this bistro classic. The simple secret to a robust flavoured broth? Caramelizing the onions.
Switch It Up!
For a milder flavour, replace beef broth with chicken. (If using chicken broth from a carton, omit water.) Or boost taste by adding 2 tbsp (30 mL) brandy or a 14-g pkg of dried mushrooms.
Try a stronger, nippier cheese, like grated asiago, or a crumbled blue cheese such as gorgonzola or stilton.
No heatproof dishes? Use an oven-safe saucepan. Create a raft of cheese-topped toasts on soup in the pan. Place in oven and broil until toasts are golden, 5 to 10 min.
